We are starting to use Crashplan for all our clients backup. This is great for files and programs that create a backup file for us.

We want to use this to also do a backup of the Exchange database.

We are looking for a cost effective way to create a backup of the exchange database (incremental) to a folder that we can then backup with the Crashplan program. If it had message level backup and restore that could be cool but at a minimum we just want a database backup we can always use Knoll program to restore information as needed.

Online backup is usually a secondary backup for us. We usually have the Windows Backup in place for local

Are you using the Windows Server Backup program? After exchange is installed you should have the VSS plug-ins to use with the backup utility to create the backup of the exchange database. Whats the exchange and server versions?
